The area is not one town but a string of hot-spring districts. Yumoto and Tonosawa sit at the bottom of the valley near the railway, Miyanoshita and Gora climb the mountain on the Hakone Tozan line, and Sengokuhara and the Lake Ashi shore spread out across the old caldera. Water sources differ between districts, so a stay in Gora can feel quite different from one in Yumoto.
Because Hakone is so close to Tokyo, it has one of the densest concentrations of rooms with their own open-air bath anywhere in Japan, from compact modern inns to old-school ryokan. Many inns also keep one or more private family baths that couples can use without booking a premium room.

How do I get to Hakone?

Tips for a private soak in Hakone
- Weekends and Japanese public holidays sell out early; midweek stays are noticeably cheaper.
- The Hakone Free Pass covers most local trains, buses, the ropeway and the Lake Ashi boats, which helps if your inn is up the mountain.
- If an inn only has a few private baths, ask at check-in for a time slot straight away.
Where to stay in Hakone for a private onsen
Yumoto and Tonosawa suit short trips, close to the station. Miyanoshita and Gora sit on the Hakone Tozan line with mountain views. Sengokuhara and Lake Ashi are quieter, and some properties there see Mt Fuji on clear days. Couples should see our Hakone couples list; for a bath on your balcony see in-room open-air baths.
